Embodiment 1

[0037] The synthesis of a kind of organic complex mercury ion probe, such as figure 1 shown, including the following steps:

[0038] (1) Synthesis of Compound 1——Rhodamine B Hydrazide

[0039] At room temperature, dissolve 0.01 mol of rhodamine B in 100 mL of ethanol solution, slowly add 0.1 mol of hydrazine hydrate dropwise, stir and reflux for 3 hours, cool to room temperature, spin dry the ethanol in the mixed solution, and add to the mixed solution Add a hydrochloric acid solution with a concentration of 1.0mol / L until the mixed solution turns red, then slowly add a sodium hydroxide solution with a concentration of 1.0mol / L to the mixed solution until the pH of the solution reaches 9-10, and filter the mixed solution to precipitate The solid was washed three times with water to obtain 3.24g pink solid rhodamine B hydrazide, and the productive rate was 70%;

[0040] (2) Synthesis of compound 2——5-formyl o-phenanthroline

[0041] The 80mL o-dichlorobenzene solution that i...

Abstract

The invention discloses an organic complex mercury ion probe and a preparation method and application thereof. The preparation method comprises the steps of enabling rhodamine B to react with hydrazine hydrate to obtain pink solid rhodamine B hydrazide, and enabling 5-methyl phenanthroline to react with selenium dioxide to obtain 5-formyl phenanthroline; enabling a reaction product obtained by reacting the rhodamine B hydrazide and the 5-formyl phenanthroline to react with Ir2(ppy)4Cl2, and then reacting with NH4PF6, thus finally obtain the organic complex mercury ion probe. The preparation method of the probe is simple, and has the advantages of stable light emission, convenient and efficient operation and suitability for qualitatively, quantitatively and quickly detecting mercury ions in a solution, soil, biological cells and the like, and can be widely applied to the fields such as environment detection and biological cell imaging.

Description

technical field [0001] The invention belongs to the technical field of chemical analysis and detection, and in particular relates to an organic complex mercury ion probe and a preparation method and application thereof. Background technique [0002] The pollution of mercury ions in the environment is increasingly harmful to human health. Elemental mercury and inorganic mercury in water can be converted into methylmercury by microorganisms, and enriched in animals and humans along the food chain. Therefore, humans at the top of the food chain are the biggest victims of mercury pollution. Acute mercury poisoning can occur when a large amount of mercury vapor is inhaled, and its symptoms are hepatitis, nephritis, proteinuria and uremia. Inorganic mercury mainly damages the kidneys and liver. Methylmercury can cause acute and chronic central nervous system damage and reproductive and developmental toxicity (Harris, H.H.; Pickering, I.J.; George, G.N. Science, 2003, 301, 1203; ...
